2.2.1. 18-Bit Multipliers

You can configure each embedded multiplier to support a single 18 x 18 multiplier for input widths of 10 to 18 bits.

The following figure shows the embedded multiplier configured to support an 18-bit multiplier.

Figure 3. 18-Bit Multiplier Mode

All 18-bit multiplier inputs and results are independently sent through registers. The multiplier inputs can accept signed integers, unsigned integers, or a combination of both. Also, you can dynamically change the signa and signb signals and send these signals through dedicated input registers.
